This invention relates to divider bars for mowing machines, and more particularly to novel means through the medium of which amowing machine having a divider board 5 may, after the removal of the board, be"

equipped with a divider bar.

The invention has for one of its objects to' provide means of the character stated through the medium of-which a divider bar may be applied to a sickle bar shoe, from whicha making any changes or alterations in the shoe, and through the medium of which the substitution of the divider bar for the divider board may be made readily by an unskilled person. Y

The invention has for a further ObJect to provide means ofthe character stated which will support the div-ider'bar in a normal position inclining upwardly and rearwardly from the sickle bar shoe, which will'permit the divider bar to swing for a limited distance upwardly from its normal position, and

which will permit the normal position of the divider bar to be raised or lowered to adapt it for use in tall and short grass.

With the foregoing and other objects in view, the nature of which will appear as the description proceeds, the invention consists in the construction, combination and arrange ment of parts herein after fully described and claimed, and illustrated in the accompanying drawing, wherein Figure 1 is a view in side elevation of a divider bar secured, in accordance with my invention, to a sickle bar shoe.

Figure 2 is a view partly in elevation and partly in vertical section of a fragmentary portionof the divider bar and the means for securing the divider bar to the shoe.

Figure 3 is a top plan view of a fragmentary portion of the divider bar and the means for securing it to the shoe, and

Figure 4 is a sectional view taken on the plane indicated by the line 4-4 of Figure 2. Referring in detail to the drawing, 1 desig shoe 1 which is rigidlysecured to the outer end of the sickle bar, and which is of wellknown construction, is provided with an The , opening 2 and a lug 3 to adapt it for the application thereto of the usual divider board andthe divider board contacted with the lug 3, which is located at the outer side of the shoe above and forwardly of theopening, to

"limit its downward swinging movement on the bolt; divider board has been removed, without;

ing 2 of the shoe Land the block 4 is located at the outer side of the shoe with the greater portionothereof extending rearwardly from thebolt. a

The block 4 is provided at itsupper front 1 corner'with a forwardly directed extension" or lug'8 whichcontacts with the underside of the lug 3 to support the'block in an upwardly and rearwardly inclined position on the shoe 1.

The block 4 is provided at its inner side with a recess 9 which is closed at its front and open at its rear end. The'recess '9 is provided for the reception of the frontend portion of the divider bar '5, and the'rear end of the divider bar is provided with an eye 10 for the reception of the bolt 7, The bolt 7 conbar 5 with respect to the block, and the downward swinging movement of the divider bar with respect to the shoe 1 is limited by the *block, The block 4 is supported in an upwardly and rearwardly inclined position in the shoe l'by the lugs 3 and 8, and the block supports the divider bar 5 in an upwardly and rearwardly inclined position with re spectto the shoe. When the divider bar 5 is V in contact with the lower flange 12 of the I to the shoe.

block 4, it is in its normal position with respect to the block, and this position of the dithe block below the lug 301' the shoe, andthe combined Weights of the block and divider bar 5 normally hold thellug of the block in c ntactlwith t clinedposition on the shoe. The block 4 and divider bar 5 are rockably. connected to the shoe by the bolt 7 for simultaneous swinging movement upwardly from and backwardly to their normal positions, the normal posi tion oi-the block being determined by the lug 3, and the normal position-of the divider bar being determined by the flange 12 or set; screw 13, which latter permits the normal position ofthe divider bar to be'varied, so asto g adapt it for use in tall and short grass.

a From the foregoing description, taken in- I connection with the accompanying drawing,. f it will be understood that the invention permits a divider bar to be readily substituted This may be done by merely; passing the bolt 7 throughthe opening .2 of. the shoe and by applying-anut 15,to the outer end of the bolt. 'lheapplication of the block 4 to the shoe positions the lug 8. of

v e lug of the shoe,with the result that the block and divider bar are supported in. anupwardly and rearwardly insignature.

ing a lug and an opening located below and rearwardly of the lug, a bolt passing through the opening, a block connected to and extending rearwardly from the bolt and having a lug contacting with said first lug, a divider bar pivoted to the bolt, and a set screw carried by the block and contacting with the lower sideof the bar and constituting means by which the bar may be adjusted with respect to the block.

In combination, a sickle barshoe having a lugand an opening located below and rearwardly of the lug, a boltpassing through the opening,ablock pivoted on the bolt and extending rearwardly therefrom and provided with-a lug-contacting with said first ing, the block being provided with a recess opening out through one side and the rear end there of,a divider bar having an end thereofpos'itioned in the recess and pivoted to the bolt,

and a set screw carried by the block and con- .ltacting withthe lowerside, of the bar and" constituting means by which the normal angularpositionofthe bar with respecttothe lock may be varied.
